Biscuits, Ghast (Giant Crocodile)

Stench. Any creature that starts its turn within 5 feet of the ghast must succeed on a DC 10 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw the creature is immune to the ghast’s Stench for 24 hours.

Turning Defiance. The ghast and any ghouls within 30 feet of it have advantage on saving throws against effects that turn undead.

Multiattack. The crocodile makes two attacks: one with its bite and one with its tail.

Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) piercing damage, and the target is grappled (escape DC 16). Until this grapple ends, the target is restrained, and the crocodile can't bite another target.

Tail. Melee Weapon Attack: +8 to hit, reach 10 ft., one target not grappled by the crocodile. Hit: 14 (2d8 + 5) bludgeoning damage. If the target is a creature, it must succeed on a DC 16 Strength saving throw or be knocked prone.
